⚠️ Safety & Precautions

• Turn the headlights and ignition off before starting.
• Let the bulbs cool first. Halogen bulbs get very hot.
• Do not touch the glass part of the new bulb with bare fingers. Skin oil can shorten bulb life.
• If your hands need more room, disconnect the negative battery cable with a 10mm wrench before working near the headlamp wiring.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open access to the back of the headlamp

• Open the hood.
• On the side with the bulb you are replacing, look behind the headlamp assembly for the turn signal bulb socket.
• If the opening is tight, use a 10mm socket and ratchet to remove the air intake duct fasteners nearby, then lift the duct out for more space.
• Work by feel first.

Step 2: Remove the old bulb socket

• Twist the bulb socket counterclockwise by hand and pull it straight out of the headlamp housing.
• If it is stuck, use a small flat-blade screwdriver gently at the locking tab.
• Do not pull on the wires.

Step 3: Replace the bulb

• Press the old bulb into the socket and twist it out, or release it from the socket if your style uses a twist-in bulb.
• Install the new bulb into the socket with gloves on.
• Make sure the bulb is fully seated and locked in place.

Step 4: Reinstall the socket

• Line the socket tabs up with the opening in the headlamp housing.
• Push it in straight and twist clockwise until it locks.
• Make sure it sits flush and does not wobble.

Step 5: Test the new bulb

• Turn the ignition on.
• Activate the turn signal and check for proper operation.
• Use the hazard lights and verify the bulb flashes correctly.

Step 6: Reinstall any removed intake parts

• If you removed the intake duct, reinstall it now.
• Tighten any 10mm bolts snugly.
• Do not overtighten plastic parts.

✅ After Repair
